Abstract：The UDRS interlocking fault is a common dose interlocking of Varian high-energy linear accelerator. Due to the complexity of the system, this fault has brought challenges to the engineers for a long time. Hence, an effective solution is urgently required. In this article, the circuit and principle for UFRS interlocking fault for Varian CLINAC-IX linear accelerator were explicitly analyzed and the maintenance methods were summarized. The management methods of such rare fault were shared, aiming to provide reference for subsequent management of similar interlocking faults.

Key words： UDRS interlocking fault Linear accelerator Dose rate
